Abstract

Double-skin timber-concrete-filled stub columns are investigated in this study. Different combinations of infills inside SHS tubes were experimentally modelled. Two types of woods as Tasmanian Oak (dowels) and Meranti were utilised as infills. The capacities versus the total weight of the new composites were evaluated. Energy absorption, ductility and stiffness were also calculated, and discussions were made comparing different composites with reference specimens of each type. The key finding was that an optimal number of dowels showed a high capacity compared to a fully concrete-filled tube while maintaining and/or reducing the total weight, which indicates an improved structural efficiency in the new composites.
